Artificial vascular anastomosis trainer and using method thereof

Abstract

The invention discloses an artificial vascular anastomosis trainer and a using method thereof. First, a fixed bracket is made on a workbench board, and two artificial blood vessels are placed on the fixed bracket. Of the two artificial blood vessels, one is a scalable artificial blood vessel, and the other is a conventional artificial blood vessel. One end of the scalable artificial blood vessel is connected with a three-phase joint, the other two ends of the three-phase joint are respectively connected with a piezometer tube and a liquid injection tube, and the mouth at the other end of the scalable artificial blood vessel faces the mouth at one end of the conventional artificial blood vessel. During operation practice, a medical care worker adjusts the scalable artificial blood vessel according to the position of the blood vessel to make the scalable artificial blood vessel and the conventional artificial blood vessel sutured together, and then, the medical care worker injects dye with color into the liquid injection tube. When the dye with color flows through the joint of the scalable artificial blood vessel and the conventional artificial blood vessel, whether there is leakage and whether there is suturing defects can be observed. Therefore, the practice efficiency of medical care workers is improved.

Description

technical field [0001] The invention relates to an artificial blood vessel anastomosis trainer and a using method thereof, belonging to the technical field of artificial blood vessel suturing. Background technique [0002] At present, the effective treatment methods for dissecting aneurysm, thoracoabdominal aortic aneurysm, and extremity large vessel aneurysm are mainly surgical artificial blood vessel replacement. However, the current problem is that the operation is risky and requires high technical requirements for surgeons. From the perspective of surgery, how to perform vascular anastomosis safely and quickly is the key to improving the success rate of surgery, reducing surgical mortality and reducing surgical complications. Key factor. Especially in the surgical treatment of severe macrovascular diseases (such as complex and extensive dissecting aneurysms), whether the vascular anastomosis can be completed quickly and safely is a prerequisite for successful surgery. ...

However, the current problem is that the operation is risky and requires high technical requirements for surgeons. From the perspective of surgery, how to perform vascular anastomosis safely and quickly is the key to improving the success rate of surgery, reducing surgical mortality and reducing surgical complications. Key factor

This is a safe and effective method, but it has high technical requirements for surgeons, and it takes a lot of operating time, and sometimes it is necessary to repair the bleeding. The current training for on-the-job doctors is to let them observe the doctor's operation, I have accumulated experience and do not have relevant practice equipment and materials, so the existing methods for practicing suturing blood vessels are still not perfect
